Ez-Control

The ez-Control is an easy to use system for bioreactors and fermentors. The system accurately controls pH, temperature, dissolved oxygen, foam/level and agitation.

The colour touch screen interface guides the user through the operation. The adaptive control features allow the user to focus on the process while the controller keeps tight control on the important process parameters. What makes this controller unique are its ease of use, its small footprint, its flexibility and its accurate control. The optional ADDA board offers an additional eight analogue inputs, four analogue outputs, eight digital inputs and eight digital outputs.

This enormous amount of additional I/O power can be used to connect biomass monitors, balances, gas analysers, variable speed pumps, fixed speed pumps valves and other equipment to the ez-Control.

Virtually any bioprocess can be controlled through the standard five control loops and the control 14 outputs. With the ADDA card the total I/O count even reaches an impressive 21 inputs and 26 control outputs. This is in addition to the two integrated alarm outputs (process alarm and device alarm). Via the integrated USB ports additional sensor amplifiers can be installed to add even more controlloops. These USB amplifiers include, biomass, fluorophor pH and fluorophor dissolved oxygen.
